Fundamental Properties of Heavily Ge‐Doped AlGaN Prepared via Pulsed Sputtering

physica status solidi (b), EarlyView.
This study explores the properties of heavily Ge‐doped AlGaN films prepared via pulsed sputtering deposition. Films with Al content below 34% exhibit higher electron concentrations than Si‐doped counterparts. The maximum carrier concentration reaches 1.8 × 1020 cm−3. Optical bandgaps are enhanced by the Burstein–Moss shift.

Toward Ultrawide Bandgap Engineering: Physical Properties of an α‐(TixGa1−x)2O3 Material Library

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
The material system α‐(TixGa1−x)2O3 has potential applications in optoelectronics as it theoretically offers a bandgap tunable over a wide range from 0.14 to 5.6 eV. In the present work, spatially addressable material libraries of (TixGa1−x)yOz are realized using combinatorial material synthesis.

Time-Dependent Real-Space Renormalization Group Method [PDF]

Journal of Sciences, Islamic Republic of Iran, 2005
In this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent Hamiltonians. We drive the time-dependent recursion relations for the renormalized tight-binding Hamiltonian by decimating selective ...

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

Advanced Quantum Technologies, EarlyView.
The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...

Cuprate Twistronics for Quantum Hardware

Advanced Quantum Technologies, EarlyView.
This review bridges decades of foundational research with emerging fabrication techniques such as molecular beam epitaxy and cryogenic stacking. By enabling control over electronic correlations and symmetry in twisted cuprate heterostructures, it highlights how cuprate twistronics could open new paths to overcome decoherence and scalability challenges ...

Research on swimming hydrodynamics based on a three‐dimensional high‐precision fish model

River, EarlyView.
Abstract Fish swimming hydrodynamics serves as a critical foundation for aquatic ecological conservation, with recent research extending from 2D to 3D perspectives. This study employs 3D high‐fidelity modeling with dynamic mesh technology to investigate how cylindrical obstacles at varying positions affect Carassius auratus locomotion. Analysis of nine

From Molecules to Bioaggregates: Unraveling the Photoexcitation Dynamics of Intracellularly Self‐Assembled Thiophene‐Based Fibers

Small Science, EarlyView.
Cell‐guided self‐assembly of thiophene based molecules inside living cells produces photostable, biocompatible nanofibers exhibiting J‐like excitonic coupling and stimulated emission. Integrated spectroscopic and quantum‐chemical analyses reveal unique photophysical behavior and low phototoxicity, positioning these supramolecular structures as ...

Real-space renormalization group approach for the corner Hamiltonian

, 2005
We present a real-space renormalization group approach for the corner Hamiltonian, which is relevant to the reduced density matrix in the density matrix renormalization group.

Discrimination of Tryptophan Enantiomers at Sub‐pm Level by Multiparametric Analysis of a Label‐Free Organic Immunosensor

Small Methods, EarlyView.
Multiparametric analysis is a crucial aspect for enhancing the final sensitivity of biosensors based on organic transistors. The traditional approaches to treat the experimental data are not always suitable to extract the correct response. In this work EGOT characteristics are processed to achieve enantiodiscrimination of free Tryptophan enantiomers ...
